SEWlNG-MACHINE TREADLE.

SPECIFICATION forming part Of Letters Patent No. 269,925, dated January 2, 1883.

Application filet] June 19, 1882 (No model.)

]0 all whom it may concern:

*Beit known that I, CHARLES M. FAIRBANKS, of New York, N. Y., have in vented certain new and nset'ul Improvements in Sewing-Machine Treadles, desoribedin thisspeuification and the drawings thereot;

The invention consists in improvements relating to the pitman and its combination Wlth the treadle-plate and driving-wheel.

Figure 1 is a side view of the improvements. Fig. 2 is a front view thereof. Fig. 3 is a front view of a portion of a sewing-rnaehine with the improvements applied thereto.

in the form of construction shown the pitman A has two hinged portions, K, having parts of the bearings B for the journal L of the treadle-plae E and the journal M of the driving-wheel P. The hinged portions are on opposite sides ofthe pitman to secure the greatest strengtln; but they maybe both on the same side, and they are especially adapted to faciliate the placing and removal of the pitman. They are held in position by set-screws N and hinges O.

Pitmen for heavy machinery have been made with yielding socket-com1ections to open at' right angles to each other in difierent planes; but these improvements differ materially therefrom in being a simple device having a hinged portion at eaoh end adapted co open in the same plane for easy attaohment to and detachment from the journals of the in eadle and driving-wheel.

The details of construction and operation may be varied within the soope of the improve- 5 ments. For example, the parts of the pitman may be held together by other means, and the hinges may be dispensed with.

I claim as my invention- The combination, in sewing mechanism, with a treadle, E, and a driving-wheel, P, or

a pitman, A, having hinged portions K to open and close in the same plane, substantially as set forth. 1

2. The combination, in sewing mechanism, 5 of a pitman having a hinged portion at eaeh end to open in the same plane, and a treadle plate and a driving wheel conneeted thereby, substantially as set forth.

3. A treadle-pitman adapted to sewing-machines, and having a hinged portion at each end to open and close in the same plane, substantially as set forth.

4. Atreadle-pitmanadaptedtosewingmechanism, having a portion of the bearing at ach end in tbe same plane detaehable to facilitate attaohment to and renioval from the journals of the treadle-plate and d riving-wheel, substantially as set forth.

In testimony'whereof I hereunto subscribe 6o.

my signature and affix my seal, in the presence of two attesting witnesses, on the 22d day of March, 1882.
